Hi I am a company.
Under the Sale of Goods Act a supplier must make sure goods supplied are fit for purpose, of suitable quality and as described.
If not then they would be liable for breach of contract.
This means that a supplier would be liable for any losses flowing from the breach/.
Therefore the supplier would be liable for additional labour and materials required.
The supplier would counter sue their wholesaler or manufacturer
So yes, they would be liable.
Can I clarify anything for you about this today please?
